FT-891 Radio Settings that cannot be double checked.

DNR, Break-in, APT and Contour are settings of the Yaesu FT-891 that reset to default if you try to check their value after you move to another memory channel. 

Now, I may be wrong, but I could not find a way out of the menu option set mode that did not save the reset value. 

See here how the programmer sets these values for you and how to check them using the programmer, even if you can't verify them through the keystrokes on the face of the radio.
